SPECIFICATION forming part of Letters Patent No. 745,764, dated December- 1, 190 3.

Application fi led January 29, 1902. Serial No, 91,760. (No model-l To all whom it may concern:

Be itknown that I, JAMES LEE BARNAMAN, a citizen of the United States, residing at'Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvements in Bed-Springs, of which the following is a full, clear, and exact description.

My invention relates to improvements in bed-springs adapted to be used in connection with the frame of a cot or bedstead; and the object that I have in view is the provision of simple and efficient means for easily taking up any slack which may occur in the article through undue stretching of the bed-spring, thus overcoming sagging of the bed and contributing to the comfort of the occupant.

A further object of the invention is to allow the head-section to be raised and sustained at an angle in order to suit the convenience of, a sick person, and, furthermore, to increase the strength of the structure, to simplify its construction, and to reduce the cost of manufacture.

. With these ends in view the invention consists in the novel construction, arrangement, and combination of parts, which will be hereinafter fully described and claimed,

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure-1 is a vertical longitudinal'section through my improved bed-spring, showing it in its taut or stretched condition. Fig. 2 is a similar View with the head-section raised to an inclined position to suit the convenience of a sick person. Fig. 3 is a plan view of the bed in the condition shown byFig. 1.

i The frame of the bed consists of the side rails 5, the foot-rail. 6, and the head-rail 7, all of which are substantially secured together byany preferred means. A bed-spring 8 of any usual or preferred construction is employed, said bed-spring being preferably of the type known to those skilled in the art as a wire mattress? One end of the wire mattress is stretched over the foot-rail 6 and is such as nails, staples, or the like. The attachment of the wire mattress to the foot-rail is'made permanent by the employment of a clamping-strip 9, which is applied over the lapped end of the mattress, saidclamping strip being disposed parallel to the foot-rail and secured thereto by a series of screws 10, or bolts can he substitutedfor the screws.

The head-rail 7 isnot as thick as the side: rails 5.01? the bed-frame, and theserails are mortised together and seen red firmly byh'olts, as indicated at 11. The siderail-soare provided with series of bolt-apertures 12, each series of apertures comprising three or more in number, and the apertures of one series being formed in one oftherails 5 ina position corresponding to the similar series of apertures in the other rail 5 of the bed-frame.

13 designatesa pair of arms which are disposed within or between the side rails 5 of the bed-frame, as shown by Fig. 3, and these arms are adj ustably and hingedly connected to the side rails 5 by means of the bolts 14. The bolts pass through suitable openings which are provided in the arms 13 and through corresponding openings in the two series of apertures 12; but these bolts may be shifted to other apertures of the series when it is desired to adjust the arms 13 lengthwise of the bed-frame in order to stretch the wire mattress and to increase the tension thereof with a view to'taking up any slack in said mattress. p

It will be recalled that one end of the wire mattress has fixed engagement with the footrail of the bed-frame, and in order to stretch this mattress its other end is clamped securely to the hinged and adjustable arms 13.

A rail 15 is secured firmly to the pair of arms by the employment of the turn-buttons 18,

the same being pivoted at 19 to the side rails 5 and adapted for adjustment across the pivoted arms 13, as shown by full lines in Fig. 3. In this position of theparts the mattress 8 is held in a taut stretched condition; but when turned'to the position indicated by dotted ings 12 in the side rails,

lines in Fig. 3, thus releasing the arms 13 and allowing the operator to raise said arms and the head section to the inclined position shown by full lines in Fig. 2. Theplampingstrip 9 is now released from the foot-rail 6 and a short section of the mattress is drawn over said foot-rail, after which the clampingstrip 9 is again secured tightly in placein order to firmly clamp the mattress between itself and said foot-rail. The operator now forcibly presses down upon the arms 13, so as to stretch the mattress, and then the-buttons 18 are turnedacross the arms for the purpose of locking them in their operative positions. It the mattress should be unduly stretched, so that the slack cannot be, taken out of the same by the described adjustment the position of the pivotal bolts 14 is changed from one opening to the other of the series of openand then the pivoted arms are pressed downward and the catches 18 are engaged therewith, thus taking upthe slack in the bed-bottom of adjustment.

The head-rail 7 is with which is provided with an eye 19, adapted to enaage a brace or 7 stay 20, the other end of which may be detaohably engaged withr-ameye 21, that is socured to one the pair of pivoted arms. 1 This stay-may be by another method or both of the rails 15 or 16 on jthe be d-frame other than the mattress 8 may be constructed either of wood orof metal, as may be found desirable.

Having thus described my invention, 1

claim as newand desire toseeureby Letters Patent- The combination with a mattress-frame and a spring-mattress, of a.v crossbar 7 fixed I to said frame and lying below the top edge of the side rails thereof, stretching-arms pivot-' said frame ally and shiftably connected to and arranged to rest on said cross-barin flush relation to the side rails, lockingplates piv n oted to the frame-rails and adjustable into engagement with said stretching-arms for clamping-bars fastened" to the stretching;- arms andengaging with said mattress;

In testimony whereof I have signed my name to this specification in two subscribing witnesses. I'
